ASDTT I do not understand why when trying to remove nvidia whatever driver eopkg MUST uninstall also doflicky
This is only true for the -modaliases
packages, which are used for hardware detection. Don't remove those (they are tiny anyway).
ASDTT DoFlicky I think is part of the problem, since the 390 version of driver removal it always said it found no drivers were found for my system.
Because it's true, there is no supported proprietary NVIDIA driver for this GPU anymore. Nouveau is the only option. None of the proprietary NVIDIA drivers in the repository will work for you.
Check if there are still any of those packages installed with eopkg li | grep nvidia | grep -v modaliases
and remove them.
